Use Laravel service providers to dynamically modify or add data configurations
DatabaseServiceProvider
extended configuration file
Create a Database service provider
php artisan make:provider DatabaseServiceProvider
Load (register) service provider, two ways
Method 1. Register in AppServiceProvider
<?php
namespace App\Providers;
...
/**
* Register any application services.
*
* @return void
*/
public function register()
{
//
$this->app->register(DatabaseServiceProvider::class);
}
Method 2. Add globally in confg/app.php
'providers' => [
...
App\Providers\DatabaseServiceProvider::class,
Extend the database configuration in DatabaseServiceProviderthe service provider
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class DatabaseServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* @return void
*/
public function boot()
{
//
$new = [
'mydb-test' => [
'driver' => 'mysql',
'host' => 'docker.app',
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
]];
$this->app['config']['database.connections'] = array_merge($this->app['config']['database.connections'], $new);
}
/**
* Register the application services.
*
* @return void
*/
public function register()
{
}
}
For testing, just connect to the database in tinker
The above code can already meet the requirements, but it is not coquettish enough.
The following code my-testis the connection subscript, and the set method will automatically set the corresponding array subscript.
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class DatabaseServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* @return void
*/
public function boot()
{
$new = [
'driver' => 'mysql',
'host' => 'docker.app',
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
];
$this->app->get('config')->set('database.connections.mydb-test', $new);
}
/**
* Register the application services.
*
* @return void
*/
public function register()
{
}
}
For the rest, you can use tinker to test whether the database connection has been added successfully.
